That's rubbish what the CSA told you. I only noticed that the flights were gone because I have monitored the development over the past few weeks considering a booking for the first week of operations. Almost all flights were available for the lowest fare (44.99 EUR) before the flights disappeared. Jetifaction has already officiall cancelled FMO-POZ and on the route to ZRH they have used a Cessa Citation or a Piper Chieftain recently instead of the Saab 340.
Really looks like a non-starter.
